CECEN

Bit 0: CEC Enable The CECEN bit is set and cleared by software. CECEN=1 starts message reception and enables the TXSOM control. CECEN=0 disables the CEC peripheral, clears all bits of CEC_CR register and aborts any on-going reception or transmission..

TXSOM

Bit 1: Tx Start Of Message TXSOM is set by software to command transmission of the first byte of a CEC message. If the CEC message consists of only one byte, TXEOM must be set before of TXSOM. Start-Bit is effectively started on the CEC line after SFT is counted. If TXSOM is set while a message reception is ongoing, transmission will start after the end of reception. TXSOM is cleared by hardware after the last byte of the message is sent with a positive acknowledge (TXEND=1), in case of transmission underrun (TXUDR=1), negative acknowledge (TXACKE=1), and transmission error (TXERR=1). It is also cleared by CECEN=0. It is not cleared and transmission is automatically retried in case of arbitration lost (ARBLST=1). TXSOM can be also used as a status bit informing application whether any transmission request is pending or under execution. The application can abort a transmission request at any time by clearing the CECEN bit. Note: TXSOM must be set when CECEN=1 TXSOM must be set when transmission data is available into TXDR HEADERs first four bits containing own peripheral address are taken from TXDR[7:4], not from CEC_CFGR.OAR which is used only for reception.

TXEOM

Bit 2: Tx End Of Message The TXEOM bit is set by software to command transmission of the last byte of a CEC message. TXEOM is cleared by hardware at the same time and under the same conditions as for TXSOM. Note: TXEOM must be set when CECEN=1 TXEOM must be set before writing transmission data to TXDR If TXEOM is set when TXSOM=0, transmitted message will consist of 1 byte (HEADER) only (PING message).

CEC_CFGR

This register is used to configure the HDMI-CEC controller. It is mandatory to write CEC_CFGR only when CECEN=0.

SFT

Bits 0-2: Signal Free Time SFT bits are set by software. In the SFT=0x0 configuration the number of nominal data bit periods waited before transmission is ruled by hardware according to the transmission history. In all the other configurations the SFT number is determined by software. * 0x0 ** 2.5 Data-Bit periods if CEC is the last bus initiator with unsuccessful transmission (ARBLST=1, TXERR=1, TXUDR=1 or TXACKE= 1) ** 4 Data-Bit periods if CEC is the new bus initiator ** 6 Data-Bit periods if CEC is the last bus initiator with successful transmission (TXEOM=1) * 0x1: 0.5 nominal data bit periods * 0x2: 1.5 nominal data bit periods * 0x3: 2.5 nominal data bit periods * 0x4: 3.5 nominal data bit periods * 0x5: 4.5 nominal data bit periods * 0x6: 5.5 nominal data bit periods * 0x7: 6.5 nominal data bit periods.

RXTOL

Bit 3: Rx-Tolerance The RXTOL bit is set and cleared by software. ** Start-Bit, +/- 200 s rise, +/- 200 s fall. ** Data-Bit: +/- 200 s rise. +/- 350 s fall. ** Start-Bit: +/- 400 s rise, +/- 400 s fall ** Data-Bit: +/-300 s rise, +/- 500 s fall.

BRESTP

Bit 4: Rx-Stop on Bit Rising Error The BRESTP bit is set and cleared by software..

BREGEN

Bit 5: Generate Error-Bit on Bit Rising Error The BREGEN bit is set and cleared by software. Note: If BRDNOGEN=0, an Error-bit is generated upon BRE detection with BRESTP=1 in broadcast even if BREGEN=0.

LBPEGEN

Bit 6: Generate Error-Bit on Long Bit Period Error The LBPEGEN bit is set and cleared by software. Note: If BRDNOGEN=0, an Error-bit is generated upon LBPE detection in broadcast even if LBPEGEN=0.

BRDNOGEN

Bit 7: Avoid Error-Bit Generation in Broadcast The BRDNOGEN bit is set and cleared by software..

SFTOPT

Bit 8: SFT Option Bit The SFTOPT bit is set and cleared by software..

OAR

Bits 16-30: Own addresses configuration The OAR bits are set by software to select which destination logical addresses has to be considered in receive mode. Each bit, when set, enables the CEC logical address identified by the given bit position. At the end of HEADER reception, the received destination address is compared with the enabled addresses. In case of matching address, the incoming message is acknowledged and received. In case of non-matching address, the incoming message is received only in listen mode (LSTN=1), but without acknowledge sent. Broadcast messages are always received. Example: OAR = 0b000 0000 0010 0001 means that CEC acknowledges addresses 0x0 and 0x5. Consequently, each message directed to one of these addresses is received..

LSTN

Bit 31: Listen mode LSTN bit is set and cleared by software..

RXBR

Bit 0: Rx-Byte Received The RXBR bit is set by hardware to inform application that a new byte has been received from the CEC line and stored into the RXD buffer. RXBR is cleared by software write at 1..

RXEND

Bit 1: End Of Reception RXEND is set by hardware to inform application that the last byte of a CEC message is received from the CEC line and stored into the RXD buffer. RXEND is set at the same time of RXBR. RXEND is cleared by software write at 1..

RXOVR

Bit 2: Rx-Overrun RXOVR is set by hardware if RXBR is not yet cleared at the time a new byte is received on the CEC line and stored into RXD. RXOVR assertion stops message reception so that no acknowledge is sent. In case of broadcast, a negative acknowledge is sent. RXOVR is cleared by software write at 1..

BRE

Bit 3: Rx-Bit Rising Error BRE is set by hardware in case a Data-Bit waveform is detected with Bit Rising Error. BRE is set either at the time the misplaced rising edge occurs, or at the end of the maximum BRE tolerance allowed by RXTOL, in case rising edge is still longing. BRE stops message reception if BRESTP=1. BRE generates an Error-Bit on the CEC line if BREGEN=1. BRE is cleared by software write at 1..

SBPE

Bit 4: Rx-Short Bit Period Error SBPE is set by hardware in case a Data-Bit waveform is detected with Short Bit Period Error. SBPE is set at the time the anticipated falling edge occurs. SBPE generates an Error-Bit on the CEC line. SBPE is cleared by software write at 1..

LBPE

Bit 5: Rx-Long Bit Period Error LBPE is set by hardware in case a Data-Bit waveform is detected with Long Bit Period Error. LBPE is set at the end of the maximum bit-extension tolerance allowed by RXTOL, in case falling edge is still longing. LBPE always stops reception of the CEC message. LBPE generates an Error-Bit on the CEC line if LBPEGEN=1. In case of broadcast, Error-Bit is generated even in case of LBPEGEN=0. LBPE is cleared by software write at 1..

RXACKE

Bit 6: Rx-Missing Acknowledge In receive mode, RXACKE is set by hardware to inform application that no acknowledge was seen on the CEC line. RXACKE applies only for broadcast messages and in listen mode also for not directly addressed messages (destination address not enabled in OAR). RXACKE aborts message reception. RXACKE is cleared by software write at 1..

ARBLST

Bit 7: Arbitration Lost ARBLST is set by hardware to inform application that CEC device is switching to reception due to arbitration lost event following the TXSOM command. ARBLST can be due either to a contending CEC device starting earlier or starting at the same time but with higher HEADER priority. After ARBLST assertion TXSOM bit keeps pending for next transmission attempt. ARBLST is cleared by software write at 1..

TXBR

Bit 8: Tx-Byte Request TXBR is set by hardware to inform application that the next transmission data has to be written to TXDR. TXBR is set when the 4th bit of currently transmitted byte is sent. Application must write the next byte to TXDR within 6 nominal data-bit periods before transmission underrun error occurs (TXUDR). TXBR is cleared by software write at 1..

TXEND

Bit 9: End of Transmission TXEND is set by hardware to inform application that the last byte of the CEC message has been successfully transmitted. TXEND clears the TXSOM and TXEOM control bits. TXEND is cleared by software write at 1..

TXUDR

Bit 10: Tx-Buffer Underrun In transmission mode, TXUDR is set by hardware if application was not in time to load TXDR before of next byte transmission. TXUDR aborts message transmission and clears TXSOM and TXEOM control bits. TXUDR is cleared by software write at 1.

TXERR

Bit 11: Tx-Error In transmission mode, TXERR is set by hardware if the CEC initiator detects low impedance on the CEC line while it is released. TXERR aborts message transmission and clears TXSOM and TXEOM controls. TXERR is cleared by software write at 1..

TXACKE

Bit 12: Tx-Missing Acknowledge Error In transmission mode, TXACKE is set by hardware to inform application that no acknowledge was received. In case of broadcast transmission, TXACKE informs application that a negative acknowledge was received. TXACKE aborts message transmission and clears TXSOM and TXEOM controls. TXACKE is cleared by software write at 1..
